That is one seriously wicked-looking bike! Kinda like a stealth fighter jet but with big, bold letters! I like how you maintained the black/white/red color theme. That was just an accident, right?

Di2 is fantastic. The only thing I'm running into is that my 7900-series Di2 features wiring that works with...nothing. All of the new frames feature cable guides and routing made for E-tube wiring. I found that out the hard way when trying to move my parts to another frame.

I have no constructive criticism on the build at all. That's rare. Bet that sucker moves!

Wheel & Sprocket....they had a bunch if OEM kits from Trek for the main pieces (F&R der, shifters, junction box A) for $500. Called them up and they helped figure out what else I needed. Came to $1K total. Again, it is the battery and charger that kills you....$300 just for those two parts!!

No, everything is working fine. I'm just trying to figure out how to charge the battery. Because of how I cobbled everything together, I may have missed something. User error, not anything with the system.

I was also checking the battery level incorrectly. I was getting a red light and thought it was almost dead. but that was because I was pressing the button to adjust the auto-trim feature, not check battery level. Again, user error.

I don't have Di2 but I recently got mechanical Durace 9000 and I will say wow. I had 7900 , 10 speed before. The new Shimano shifting is really sweet, a huge upgrade in feel. I ran the new cables in my old housing. Installation and setup was pretty easy. They changed some off the entry / exit points so you have to look around a bit to find them, but it went smooth enough
